I had created a Dashboard using Tableau 8. I am NOT using any EXTRACT on this dashboard. I have directly connected to database (using only one table). Now my question are: - If dashboard is published, does dashboard will be refreshed every time when dashboard is open? - If not, what I need to do so that dashboard will refresh while it is opening ?
By default, the dashboard will use cached data, if it exists. You can make sure you have the latest/greatest data by clicking the "Refresh Data for this View" button on the toolbar after it has rendered.
You may also want to consider changing how Tableau Server does caching so that you can have "fresher" data.
